I am part of the team that developers a multiplatform algebra teaching game for kids (DragonBox). The touch interface is very intuitive and practical for this type of applications. It allows very rapid & natural interaction, harder to emulate using keyboard&mouse for young users.

Thanks a lot! Our goal is to teach the K-12 math curriculum in 30 hours. DragonBox is our proof of concept. Expect more goodies from us in the future!

We (the founders) are French, and based in Norway and France.

Shameless plug: for those who have kids a little bit older, DragonBox is our algebra educative game. And we're preparing the Linux version: http://support.dragonboxapp.com/forums/166049-general/suggestions/2946059-release-a-version-for-pc-either-linux-or-windows

Drop us a line if you think this is interesting!

As for personal advice, for 3yo: GCompris

I live in a European state without death penalty. By your logic, as US legally murders way more people than we do, per capita, it should have way much less people in jail as we do, per capita.

Fail...

France and Germany have around 8 times less people per capita in jail than US. http://www.nationmaster.com/graph/cri_pri_per_cap-crime-prisoners-per-capita

Everybody knows that nails get dirty. So instead of educating my kids to wash their hands before they eat, I nail-circumcised their nails when they were born. That way, no more diseases. And you know, 10 years later, they feel OK with that. They never remember having nails. And they didn't get a disease at all. Proof!

Some naysayers mention that the kids on the other side of the fence did get some disease one day, even though they are nail nail-circumcised. That's because their parents let them play everywhere. They should practice playground-abstinence like my kids, and put on their preservahand gloves when they go to school.

I suspect one should maybe let kernel developers answer those technical questions themselves ?

For example Ted Tso's answers points out to some things that fall in the scope of the feasible given Nvidia's developer constraints:

And Mathew Garret's tips for splitting to open kernel/closed userspace architecture as also valid:

A nuclear weapon isn't defensive. At best, it is persuasive or counter-offensive.

Defensive technologies would be: a shield, a satellite with lasers, etc.

Unity3d also supports Mono and is cross platform (iOS, Android, Mac, Windows, web, etc...). It's not nuts at all.

I find this use of the technology really appealing. As "enjar" writes below tablets aren't bad themselves. It's how we use them. It's all about not falling into excess and providing diverse experiences to people.

As for math learning, I am working on an ipad app that we will release in a few weeks. It is intended for the masses but I believe it will as well help a lot of people in the situation of your sister. If you're curious our (freshly set up) site is at http://wewanttoknow.com

And good luck with your sister, it seems she is lucky to have you taking care of her!

"if you let your friend joyride the car off the record you are putting the other co-owners in a losing situation"

assumption

* maybe my friend would never have bought the car in the first place
* maybe he instead will buy it after the joy ride, or do something else positive (recommend the car, buy the next model, go to a car expo, buy car manufacturer tee-shirts)

So according to you
* printing, storing, shipping costs are not a large part of the book price as Extra costs (marketing, etc) are to be applied
* this is only valid for large scale sales as low scale aren't envisioned due to poor viability
* because of large scale, they need to have large marketing costs, increasing the cost ratio of these Extra activities
* because of large scale, publishing costs get lowered per item, thereby reducing its ratio

The publishing costs are just low per item because the system is focusing on large scale printing to actually lower the distribution costs per item...

Aren't you just describing an inefficient system that justifies itself ? I say cut the inefficient part.

According to http://ireaderreview.com/2009/05/03/book-cost-analysis-cost-of-physical-book-publishing/

And author's get 8/15% of a book. That's a bit small to me. And that's in part caused by this inefficiency.

I agree.

I would have paid one dollar for the app. Maybe CBS wants to reconsider instead, contract the developper to modify the app. If they keep the open source version, they could have a different theme for the OSS one.

Win-win ?

I haven't found a petition. Is there one ?

So one can block the sale of a device on a whole continent because it possibly infringes on a functionality that represents 1/10000 of the default functionality of the phone. My phone can call, video call, chat, do my email, take and edit videos, upload pictures to the net, scan bar codes for maintaining list of books and dvds, do anything a browser can do, play games like a console, be my alarm clock, and I can't buy it because of the way it reacts if I scroll half way my pictures in the photo editor ?

This is just wrong.
